Lysander au Lune (born 733 P.C.E.) is the grandson of former Sovereign of the Society Octavia au Lune. He was Octavia’s heir until her deposition by Virginia au Augustus in 743 P.C.E. After The Rising, he fell under the guardianship of Cassius au Bellona, and spent his formative years with Cassius in exile, rescuing imperiled ships around the Asteroid Belt.
Grandson of the deposed Sovereign, Lysander au Lune was spared by Darrow ten years ago on the condition that he would live under the tutelage of Cassius au Bellona. When investigating a crippled ship in deep space, Lysander and Cassius rescue a mysterious Gold woman and, in doing so, are thrust into the center of a violent coup among the Golds of the Rim. Will Lysander follow Cassius’ teachings, or will he choose to forge his own bloody destiny among the Golds? 
Lived on Luna ever since the death of his parents. Groomed by Octavia to be the next Sovereign. He sees Darrow as his a childhood hero after witnessing Darrow's campaign and siege of Olympus during his years in the Institute.
Lysander is quite innocent and very honest, taught to never lie. He is brave for his age, overcoming fear to behave reasonably and with calm even in intense and dangerous situations.
Apparently his eyes were so bright they were like golden crystals.
- Lysander was a Spartan general that defeated Athens, and the first Greek to have gained a cult.
